30317DU is high-load metric single-row tapered roller bearing complying with ISO & NTN industrial specifiions, overall dimension 85×180×44.5 mm, widely applied in commercial vehicles and heavy machinery drive systems.
Manufactured from high-hardness quenched GCr15 bearing steel, equipped with stamped steel cage to evenly guide tapered rollers. D upgraded roller profile greatly extends service life under vibration and impact conditions; U universal tolerance ensures cross-brand interchangeability. Open unsealed design adapts perfectly to oil bath circulating lubriion inside closed axle housings and gearboxes, with outstanding heat dissipation performance. Single-row tapered structure bears simultaneous heavy radial load and one-way axial thrust, commonly used in back-to-back paired arrangement to realize bidirectional axial positioning for truck axles, drive shafts and transmission assemblies.

Q1: Exact overall dimensions?
A: Inner bore 85 mm, outer diameter 180 mm, total assembled width 44.5 mm.
Q2: What do suffix D and U stand for respectively?
A: D = optimized enhanced internal structure for higher load capacity; U = universal interchangeable tolerance for cross-brand replacement.
Q3: Seal Type?
A: Open Type, no rubber/metal dust seals on both sides.
Q4: Can single bearing bear bidirectional axial loads?
A: Single unit only withstands one-way axial force; two bearings mounted oppositely can bear bidirectional axial loads.
Q5: Two limiting rotation speeds?
A: Grease lubriion: 1900 rpm; Oil lubriion: 2500 rpm.
Q6: Can it be used on exposed outdoor rotating shafts?
A: Not suitable. Open structure must rely on closed equipment housing to block dust, mud and moisture.
